Im very confused about the difference between credit memo and refund. Magento documentation states the following :
A credit memo is a document that lists the amount that is owed to the customer. The amount can be applied toward a purchase, or refunded to the customer. You can print a credit memo for a single order, or for multiple orders as a batch, or group. Before a credit memo can be printed, it must first be generated for the order.
But when we try the feature, on a paid order, all we can do is a refund offline. There is no option whatsoever to credit customer account for a futur purchase. Its like if this following statement is false :
The amount can be applied toward a purchase
We couldnt find any reference on the Internet explaining how to apply the credit memo toward a purchase or attach it to the customer account.
Does this feature just not exists ?
